I have setup my MQTT and Influxdb connection already and it is working quite good for a while now.
Now i want to add some let's call it "advanced functionallity". So a little backround information: I have multiple sensors (temperature, humidity etc.) in my home installed and all are sending their values in the data base, but every sensor is sendy by change so i have different time stamps for each single sensor/value. Is it possible with a node-RED function to get all sensor values from one type e.g. all temperatures and store them into an array and if one value changes the complete array of values will get pushed into the database? So e.g. 15 sensors are connected with this node and one value changes than all 14 values (previous values) would be send again and the new one value will be sended with the updated value?
I'm thankfull for every hint to get it working
